Which of the following statements about estuaries are true?
A. They are the gateway to freshwater breeding grounds of some marine animals
B. They are the breeding grounds for many types of aquatic animals
C. Estuaries are resistant to pollution because the constant inflow of freshwater flushes the pollutants out into the ocean.
D. They are areas where freshwater streams or rivers merge with the sea
Estuaries are located where rivers meet the sea. Estuaries are home to diverse plant and animal groups that have adapted to brackish water. Therefore, option A, B and D are correct.
What are estuaries?Estuaries and the wetlands that surround them are types of bodies of water that may typically be found near the point where rivers meet the ocean. Brackish water is a mixture of fresh water that drains from the land and salty water from the ocean. Estuaries are home to a wide variety of plant and animal populations that have adapted to brackish water.
Seagrass, mangroves, saltmarsh, macroalgae, and microalgae are the most common types of plant communities that may be found in our estuaries. Plants that are able to survive in estuaries are able to withstand a wide range of environmental stresses, including shifts in salt or water level, rainfall, currents, and current direction.

Flowering tundra plants must bloom and set seed quickly because _____.
Answer:
the summers are very short.
Explanation:
Tundra is a type of biome located in the northern hemisphere of the planet, in regions near the Arctic, more precisely in northern America, Europe and other places such as Alaska and Siberia. These regions tend to have very short summers, however summer weather conditions are extremely important for the reproductive process of these plants, so they must bloom and set seed quickly.

In three sentences or fewer, explain the difference between using geothermal energy to generate electricity and using the geothermal gradient to heat your home with an underground heat pump.
Tapping of geothermal energy to produce electricity is done on a larger scale compared to the tapping of the geothermal gradient using a geothermal heat pump. Harnessing geothermal energy is also reliant on geological conditions such as in the area of convection boundaries while geothermal gradient can be harnessed virtually anywhere on the earth surface.
Final answer:
Using geothermal energy for electricity involves tapping into geothermal activity, like hot springs near the Earth's surface, while geothermal heat pumps use the stable underground temperatures to efficiently heat or cool homes.
Explanation:
The key difference between using geothermal energy to generate electricity and using the geothermal gradient for heating with an underground heat pump lies in the method and location of heat extraction. Geothermal power plants require specific geothermal activity near the Earth's surface, such as hot springs or volcanoes, to produce electricity. In contrast, geothermal heat pumps use the constant temperatures found 20 feet below the surface to heat or cool homes efficiently, capitalizing on the subsurface as a heat source in winter or a heat sink in summer, and thus conserving energy that would otherwise be used for conventional heating or cooling systems.

Which is referred to as the "walking larva" of the blowfly? 1.first instar 2. second instar 3. third instar 4. pupa
Answer
1.First Instar
Explanation
In biology of insects, there are 1-7 instars. The first instar is quite mobile and has long legs with which to disperse. At this stage, it explores cracks, and depressions in the soil in search of an egg pod. After the first instar, the larva moves little because the legs become smaller and smaller.
describe three parasitic flagellates and their vectors
Three parasitic flagella and their Vectors:
1. Giardasis is a parasite that causes diarrhea or Giardia Lamblia infection in humans and animals It infects the small intestines of Human beings and animals once they ingest Giardia cysts from contaminated food and water or fecal-oral route. Plasmid or prokaryotic DNA is the vector for this parasite
2. Trypanosoma cruzi is a parasite that causes Chagas disease. These parasites occur in the bloodstreams of man but do not multiply there. Vector for this parasite is hemipterous or kissing bugs.
3. Trichomonas vaginalis is a parasite that can be found in the vagina of women and urethra of men.This parasite does not survive more than 24 hours outside the body of the host. Vector for this parasite is the human male.
Final answer:
Three parasitic flagellates include Trypanosoma species, which cause sleeping sickness and Chagas disease via insect vectors; Giardia lamblia, causing giardiasis through contaminated water; and parabasalids, responsible for diseases like trichomoniasis.
Explanation:
Parasitic flagellates are protozoa that can cause diseases in humans, often requiring vectors for their transmission. Three notable examples include:
Trypanosoma species, which cause sleeping sickness in Africa and Chagas disease in South America. They are transmitted by insect vectors such as the tsetse fly (for sleeping sickness) and the triatomine bug (for Chagas disease).Giardia lamblia, responsible for giardiasis, a diarrheal illness. Transmission occurs through the fecal-oral route, usually by ingesting contaminated water.Parabasalids, such as those causing trichomoniasis, transmitted through sexual contact or contaminated surfaces. These organisms move with flagella and affect various tissues in the human body.These parasites enter the human body through different routes but share a commonality in requiring either direct contact with contaminated materials or an insect vector for transmission.

Which vessels allow diffusion of oxygen and nutrients across their cell layers?
Answer:
Capilleries
Explanation:
Capillaries are the places where the exchange of substances between blood and surrounding tissues occurs. Substance exchange can occur between and through the cells that make up the vessel wall. The pores present in some types of blood capillaries also act as transfer sites. It is noteworthy that the permeability of these vessels varies from one body region to another. In summary, we can say that it is the capillaries that allow the diffusion of oxygen and nutrients through their cell layers.
Blood capillaries are vessels of the cardiovascular system that are characterized by their small caliber.
Tina's second cousin was diagnosed with asthma at age 5. what would be included in your treatment plan? what factors might concern you related to compliance?
Asthma can be treated with breathing exercises and by using long term medication such as inhaler and nebulizer. After using an inhaler or nebulizer the person has been advised to breathe in and out ten times. Some children are afraid of nebulizer that makes that less effective.
Further Explanation:
Asthma is an inflammatory lung disease. The common symptom of this disease is difficulty in breathing. It does not allow the person to do physical activity. The center for disease control and prevention (CDC) estimated that around twenty-seven million Americans have asthma. According to them twenty-seven it is the most common disease among the American children.
The symptoms appear when the linings of the airways swell due to the muscles that the exercises present around them has. It leads to accumulation of mucus in the airways that result in a decrease in the amount of the exchange. The symptoms include tightening in the chest, shortness of breath, coughing and fatigue.
The asthma gasin two ways namely; breathing exercise and long term asthma. The doctor recommends the right treatment or a combination of treatment. Breathing exercise helps in getting the required amount of gases in and out of the lungs. It increases the capacity of the lungs. Inhalers and nebulizers are the long term medication that helps in controlling asthma.

The Northeast’s rocky and jagged shoreline provides many _____.
Final answer:
The Northeast's rocky and jagged shoreline offers various opportunities for tourism, including sights and recreational activities. They are shaped by wave action, and their diversity ranges from cliffs to sandy beaches, important for both ecological health and the local economy.
Explanation:
The Northeast’s rocky and jagged shoreline provides many opportunities for tourism, including sightseeing, hiking, and recreational activities such as sailing and fishing. The complex coastline, shaped by the sediment transported by wave action, contains well-sorted gravel and sand, indicating a high-energy environment where wave action is strong. Destinations like Island Beach State Park in New Jersey are examples of this, showcasing the natural beauty and geological features that attract visitors.
These coastlines are diverse, varying from steep cliffs to sandy beaches and coves, often protected from extensive wave damage due to their orientation, as is the case in parts of the Mid-Atlantic States. Moreover, the shoreline's ecological health can be affected by the proximity to human settlements and their activity. Therefore, sites like Santa Cruz Island off the California coast, exhibit a range of habitats for both wildlife and human enjoyment while highlighting the need for conservation and careful management of these delicate coastal ecosystems.
In regions like New England, both the mountains and the coastline provide a dual attraction for tourism and activities such as skiing and summer vacations. The dynamic and varied coastal geography offers a wealth of opportunities for both recreation and the economy in areas like finance, telecommunications, and healthcare, making these coastlines invaluable to local communities.
